In response to the complex working environment and nonlinear characteristic of new energy converter (NEC), the control method based on self-stable region and modeled dynamic feedback was proposed. Nonlinear mathematical model of NEC with LC filter was rebuilt, modeled and unknown nonlinear dynamic were separated; without considering the modeled dynamic, the existence condition and proof process of self-stable region were presented, and the design method was given; by introducing the modeled dynamic feedback, a novel control strategy for NEC system was established. The experimental platform based on the prototype of single-phase NEC was built, both steady and dynamic experiments were implemented, and the results verify that the proposed method achieves the stable control of the NEC system.
